In all seriousness, the bolded I would say is not any better. People have been warned/suspended for similar attempts at wordsmithing in the past.
In most cases, there really isn't that much variability between someone saying "You're a POS," "Are you a POS?" or "anyone with that opinion is a POS." The last example has been attempted many times, but again, the messaging/implication there is obvious when it is clearly made in reference to specific conversations or posters. In this case, it would've been pretty obvious what message was trying to be conveyed.
The best way to deal with disagreeable opinions is to either a) ignore them or b) keep the reply specific to the disagreeability of the opinion. For example, Apsu's post was pretty bad, but there were ways to attack the ridiculousness of it without bringing his character into it. For example, you could've said "Is this sarcasm? A failed attempt at humor? If not, that's an awful opinion and it's ridiculous to think that's OK" or something along those lines.
I get it. It doesn't have quite the same firepower or satisfaction, but it would've kept you off the radar.
